Ah yes, I see some now, but they're buried, in part because of the higher prices.
But pricing, say, OGG-HNL-MSP-NYC in first/business class comes out ~$400 higher than booking a separate FC ticket on OGG-HNL plus DL HNL-MSP-NYC, though it seems HA won't check the bags through (?) so you'd probably need to take an earlier OGG-HNL flight if booking separately just to leave time to collect and re-check.
